Problems solved by technology

[0004] However, the simulation effect of WRF will be affected by terrain, underlying surface, resolution, driving field and physical process. It is difficult to accurately predict meteorological elements based on a single WRF model, especially in areas with complex terrain. The simulation accuracy of WRF model Not accurate enough, often unable to meet actual needs

Abstract

The invention relates to a weather forecast element correction method and device, computer equipment, storage equipment and a computer program product. According to the weather forecast element correction method and device, actual weather element data of a specific area and weather element data of numerical mode forecast can be corrected; in particular, meteorological element revision can be carried out on coastal areas and other areas where extremely severe weather easily occurs, and the accuracy of meteorological element prediction is improved. The method comprises the following steps: collecting a numerical weather forecast file which is output in a WRF mode and aims at a preset area; wherein the numerical weather forecast file comprises predicted numerical values of various meteorological elements; interpolating the predicted values of the various meteorological elements to longitude and latitude grid points of a preset area by using a nearest neighbor interpolation method to obtain interpolation results; and inputting the interpolation result into a pre-constructed support vector machine model for calculation to obtain a revision value of each meteorological element.

Description

technical field [0001] The present application relates to the technical field of meteorological forecasting, in particular to a method, device, computer equipment, storage device and computer program product for correcting weather forecast elements. Background technique [0002] The icing disaster of transmission lines is one of the most serious meteorological disasters in the power system, which seriously threatens the safe and stable operation of the power grid. In recent years, extreme weather has occurred frequently, which has brought great pressure to the transportation facilities of transmission lines, and the failure of transmission lines has easily caused huge losses to the economy. [0003] In order to reduce the loss caused by freezing disasters to transmission lines, it is necessary to accurately predict the icing thickness of the conductor in advance, that is, the prediction of the icing thickness of the transmission line. , wind speed, wind direction, air press...
